A conventional single-way clutch (S.W.C.) or an over running clutch (O.R.C) has following transmission features:

when an active side is driven in one rotational direction, e.g. the clockwise direction, a passive side is able to be linked; on the other hand, when the passive side is driven in the counterclockwise direction, the active side is able to be linked;

when the active side is driven in the counterclockwise direction, the passive side is not able to be linked; when the passive side is driven in the clockwise direction, the active side is not able to be linked, the abovementioned are its transmission features;

when the active side is desired to be driven in one of the directions, e.g. the clockwise direction, the passive side is able to be linked for rotational outputting, and when the passive side is driven in the counterclockwise direction, the active side is not able to be linked, which is not the function that the conventional single-way transmission device can provide.
